An 84-year-old woman visited our department because of a mass in the alveolus of the anterior maxilla. The lesion was pedunculated, measuring 11 × 10 mm, and hard in consistency. A dental radiogram revealed a radiopaque core, which was connected to underlying alveolar bone. Under a clinical diagnosis of fibrous hyperplasia with bone formation, the lesion was excised by cutting its pedicle with a bone chisel, and the underlying bone was smoothed with a bur under local anesthesia. Pathological examination demonstrated the formation of bone, which was covered by cartilage in the submucosal connective tissue, and osteochondroma was diagnosed. There has been no recurrence as of 3 years 4 months after the operation.
